I DUMP-CAR,

naisae'pem Be it known that I, EDWARD PossoN, a citizen of the UnitedStates, residing at Chicago,

mthe county of Cook and State of" Illinois,

have invented certain new and useful rovements in Dump-Cars, of which the ,fol-

- owing is a specification.

My mvention relatesto' dump-cars of the type in which the bottom is composedsubstantially entirely of dum ing-doors, forming e doors are-closed,

the ordinary gondola car. i A

My invention has for one of its objects to vrovide improved means for operating the ump'ing-doors. Other objectswill appear from the following description of my. inven tion.

and claims. In the drawings, Figure 1 is an end eleva-. tion of a portion of my car, showing a part of the end sill and the door-.0 erating mechan 1 the parts shown in Fig. 1; Fig. 3, an end view of a portion of the end sill, viewed from theinside, showing a part of the o'perating meohanism; Fig.4, a

longitudinal section on the line '4 ofFig. 1;

Fig. .5, a transverse section on the line' 5;of H v 4;-'Fig'.- 6, a longitudinal sectional view of a portion of the car, showing the structure at.

one of the intermediate cross-sills; Fig. 7,. a

' view similar to Fig. 6, showing the structure 35.

at the center cross-sill; Fig. 8 a plan view of one of the doors; Fig. 9, aside elevation ofthe 'door and Fig. 10 an end el'evation..thereof'.

Referring to the drawings, it indicates the center sill; b, dumping-doors hinged thereto. e, e, and e represent, respectively, the,end

sill, the intermediate cross-sill, and the center cross-sill. The end and intermediate crosssills are. provided with. inclined slots e the shaft at this Mounted in these slots is a shaft (1, extending from the end sill of the car to the center sill e a thereof, where it is" supported in. a manner ward the center sill the doors presently to .be descri "-provided at intervals with rollers c, against the under side of the hi1 1ge'ddunipv .ing '-doorjs.'

ed. This shaft ii is hearing Itwill be readily understood that when the shaft is moved in a direction toted to' drop, while they reverse movement of the shaft will close the doors.

In order to operate the doors, I provide the followingmecha'nism: Upon the end of the g Specificationof Letters Patent. Application filedl'ebruary a 1906.. Serial it. 300,152.

shaft outside the end sill is mounted a ratchet f. Loosely mounted on the shaft adjacent the ratchet-wheel is an operating-lever f which may be made as shown in- Fig, 2, in whichthe lever is shownend adjacent the ratchet-wheel with abifurcated portion between which bifurcated as provided at its portions 1s provlded a pawl f engagin the I sha t in anyposition to whichit may be adjusted;

-jacent the lower edge of its slotted portion On the inner side of the end sill and ad-. '-f

mounted a rack-bar m, the teeth ofiwhich, I

m, 'are formed by outwardly-projecting stud's,as-clearly shown in Figs. 3 and 4, these studsfhavmg spaces betweenthem. Secured engaging the to the shaft is a' ear-wheel m studs. j This rac -bar and its gear-wheel forma simple and taining means forthe door-operating device, .andit will-be noticed that by roviding the spaces betweenthe' teeth or stud on, so that the rack-bar will be en'tirely clear at all times." The intermedlate sills, as

.shown in Fig. 6, are provided with a rackbar A; similar to the rack-bar m at the end sill, the rack-bar hbeing provided with teeth or studs h. At the intermediate sillsthe o erating-shaft is rovided with a gearw heel d engaging t e teeth of therack-bar,

and with rollers d engaging the. lower face of efiicient .guidingand re-1 .S of the rackbar no dirt or obstructions can remain therethe slotted portion of the sill. To hold the gear-wheel d in position andto strengthen oint, I provide an elongated collard, integra with the gear wheel and eX- tending forsome distance along the-shaft.v U on this collar the roller 0 is loosely mount- 0 at the centersill, whereas shown in Fig. 7, the end of the'operating-shaft is provided This roller is supported u on a track k fornning a. portion of a rackar 14, similar to the rack-bars m and h above described The rack-bar 7c is securely fastened to the center sill and is provided with the spaced teeth or projections k. Along its d pper edge the I o 5 with a roller is, corresponding to the roller d above described.

' It will operating-shafts on each side ofthe car, ex-

- sired manner; but I have engaging the racks,

' the ratchet-bar, and

In order to brace and strengthen the parts and also support the operating-shaft near its end, I connect the center sill and the side sills g by a channel brace-bar '11., (shown in Figs. 4 and 5,) and the shaft at this point .s

provided with a roller n, traveling upon the upper flange of this channel-bar. In order to further strengthen the shaft, also, I provide it at this point with a collar n extending from the roller n. to the gear-wheel m which is provided also with an elongated collar m be understood that there are two tending from the end sills' to the center sill, as indicated in Fig. 7

The doors may be constructed in any deprovided a door made as followsandshown in Figs. 8, .9, and 10: The door I) is composed of a series of narrow planks a, beveled at their ends, as shown in Fig. 9. The ends of this door are bound by a metallic binding-strip 0 extending over the top and bottom faces of the door and the ends thereof. On the bottom face the binding extends inwardly for. some distance. Adjacent the front edge of-the door, on the lower face thereof, I provide an angle brace-stri 0 secured to the door and to the end binding-strips. The door is further braced by a center brace-strip 0 which is secured to the door, as shown, this center strip passing beneath a downwardly-bent portion 0 of the angle brace-strip 0, as shown 1n Fig. 9. Along its inner edge on its dumping-face the door is provided with a braceplate 0 which extends beyond the edge of the door, as shown, and is downwardly turned, so as to pass beneath a metallic strip '0, secured to the center sill, as shown in Fig. 5. Metallic-strips orloops 0 are secured to the lower inner edge of the door, forming a portion of the hingethereof, as shown in Fig. 10. v

I claim- 1. A dump car having the usual framework, dumping-doors hinged to the center sill, a shaft mounted in the cross-sills beneath the doors, ways in the cross-sills in which the shaft is movable to open and close the doors, racks on the cross-sills provided with lateraliy-projecting teeth, there being. openings between adjacent teeth, pimons on the shaft a ratchet-bar on one of the cross-"sills, a pawl on the shaftengaging shaft.

2. A dump-car having the usual longitu- -secured to the upper face means for operating the each having one end resting on one of the tracks on the center cross-sill, dumping-doors hinged to .the longitudinal center sill supported by the shafts, and means for operating and holding the shafts.

4. A dump-car having the usual framework and having its bottom compose substantially of dumping-doors, a shaft beneath the doors for supporting and operating them, inclined ways on the cross-sills upon which 'the shaft is movably supported, and auxiliary inclined tracks for the shaft extending from the center sill to the side sills of the car. 5. A dump-car having the usual framework and having its bottom composed substantially of dumping-doors, a shaft beneath the doors for supporting and operating them, inclined ways on the cross-sills upon which the shaft is movably supported, a channel bar connecting the center and side sills between adjacent cross-sills and forming an inclined auxiliary track for the shaft.

6. A combined rack and track for car-doorsupporting mechanism, consisting of a metallic plate having an upper horizontal fiange forming a track and having a vertical flange provided .with a series of spaced laterallyprojecting teeth.

7. A0ar-door-supportingmechanism,comprising a shaft beneath the doors and bodily movable to operate the doors, rollers upon the shaft engaging the doors, racks mounted in the framework of the car, and pinions upon the shaft en aging the racks, said pinions being provided with longated co'llars, substantially as described.

8. In a dump-car, series of planks, channel brace-bars on the ends thereof suitably secured thereto, a center transverse brace-b ar secured to the under side thereof, a' longitudinal angle brace-bar secured to the under side thereo adjacent its forward edge, a rear brace-and cover-plate of the door along its inner edge and projecting over said edge, and a series of metallic loops secured to the under face of the door along its inner edge.
